HEAD-BLOCK.

Specification of Letters Patent.

Patented Dec. 14, 1920.

Application filed June 22, 1920. Serial No. 390,802.

To all whom it may concern:

Be it known that I, JOSHUA ROSSINI, a citizen of the United States, residing at Olyphant, in the county of Lackawanna and State of Pennsylvania, have invented new and useful Improvements in Head-Blocks, of which the following is a specification.

This invention relates to head blocks for stopping cars at certain points along the track, the present invention being an improvement over that patented by me on December 9, 1919, No. 1,324,271.

The object of the present invention is to improve the patented device by providing a.shoe on the wedge block for engaging the car wheel with means for yieldingly holding said shoe in proper position, also to make the device adjustable to fit different sizes of rails and to provide means for limiting the downward movement of the wedge block.

Another object of the present invention is to provide different ways of moving the wedge block out of wedging position and also to provide means whereby the device can be easily handled.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a view showing the application of my invention.

Fig. 2 is an elevation of the device itself.

Fig. 3 is a section on line 33 of Fig. 2.

Fig. 4 is a view of the wedge member and its shoe end parts in section.

Fig. 5 is a section on line 5-5 of Fig. 4.

Figs. 6, 7, 8 and 9 are detail views of the filler platesfor making the device fit smaller sizes of rails.

In these views 1 indicates the track and 2 indicates a car the wheels 3 of which engage the track. 4: indicates my improved device which as adapted to be clamped on the rail of the track to engage the wheel of the car to prevent further movement of the car. The device consists of the two members 5 which are provided with the barrel portions 6, of a hinge, intermediate their top and bottom edges. A pin 7 passes through the barrels to hinge the two parts together. The

lower portions of the members are grooved as at 8, to provide the jaws 9 for gripping the rail. The upper portions of the members are each provided with an extension 10 at one end thereof and said extensions are provided with holes to receive a pin 11 which also passes through a hole 12 formed on the bottom of the wedge block 13. This wedge block is adapted to extend between the members to force the jaws toward each other to grip the rail. This wedge block is of greater width at its pivoted end than at at its free end and its lower edge flares upwardly from the lug. The extreme free end of the wedge block is reduced to provide a handle 15 and the upper part of the block is formed with an opening 16 to form a handle 17. This block may be made hollow if desired to reduce the weight thereof. Adjacent the handle 15 the block is provided with a screw threaded hole 18 which receives the bolt 19, the head 20 of which is adapted to engage the hinge and thus limit the movement of said block. By adjusting the bolt in the hole the limit of movement of said block will be controlled. The bolt may carry an eye member 21 which is adapted to be carried by a link or the like with the eye of the pin 22 which is carried by the pin 7 In this way the block may be locked against movement. The head of the pin 7 bears against the lug 12 and thus serves to prevent the bending of the pin 11, which connects the block with the jaw members. The wide end of the block is made straight and a shoe 23 has its convex face engaging said end and this shoe is pivotally connected with the block by means of the pin 24 passing through ears formed on the block and shoe.

The shoe is normally held against locking movement on the block by means of a spring bar 25 secured to the block by the pin 26 and having its end located between the lugs 27 formed on the ear and the shoe. A guard member 28 is secured to the block and surrounds the pin 26 and this guard is provided with a notch 27 through which the spring bar passes and the walls of which limit the movement thereof. The concaved face of the shoe is provided with grooves 29 for receiving a bar or the like to force the wheel of the car away from the shoe. An extension 30 may be formed on the lower part of the block adjacent the lug 12, this extension being located below the shoe and adapted to lie a short distance above the tread of the rail. The pin 11 may be withdrawn and a crow-bar or the like placed between the tread of the rail and the extension 30 to force the wedge block from-between the jaws. The block -mayalso be removed from between jaws by means of a crow bar and fulcrum lock, the bar engagin the handle 15 as shown in dotted lines in Fig. 1.

The device is placed on the rail and clamped thereon by pushing the wedge block between the aw members. When the shoe is struck by the wheel the blow will force the block downwardly and thus cause the jaws to grip the rail more firmly and so prevent further movement of the car. The flexible connection between the block and shoes will permit the shoe to accommo date itself to the wheel, no matter what position the wedge block is in.

v I provide the jaw members with reinforcing ribs 31 and with a handle 32.

V I also provide means for making the device fit rails of different sizes. In Figs. 6, 7 and 8, such means consist of a pair of plates 33, each provided with a pair of stems 34 with engaging holes 35 formed in the jaw parts, the plates being held in position by cotter pins fastened to the holes in the stems. I also provide a plate 36 having upwardly extending perforated lugs 37 at its ends for engaging the hinge pin 7. Thus when the device is to be used on a small rail the plates 33 are placed in the grooves 8 to engage the sides of the rail head and the plate 36 is suspended from the hinge pin and is adapted to engage the tread of the rail. These plates act as fillers as shown in Fig. 8:

In the modification shown in Fig. 9 a channel member 38 is provided to take the place of the plates, the crosspiece of the membercarrying the lugs 39 which are perforated to receive the hinge pin. The outside corners are cut away as at 4:0 to permit the side plates or flanges to have movement relative to the cross piece so that the jaws will cause said flanges to grip the rail. This member is used in the same manner as the plates 33 and 86.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent. I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall with in the scope of the appended claims.

W hat I claim is 1-- 1. A. device of the class described comprising a pair of jaw members hingedly connected together, a wedge block located between the jaw members and pivoted thereto and a shoe pivotally connected with the mally holding the shoe in a certain position.

3. A ,device of the class described comprising a. pair of jaw members hingedly connected together, a wedge block located between the jaw members and pivoted thereto and adjustable means for limiting the downward movement of the wedge block.

4.. A device of the class described comprising a pair of jaw members hingedly connected together, a wedge block located between the jaw members and pivoted thereto and means for limiting the downward movement of the wedge block, said means consisting of a screw bolt carried by the block and having its head adapted to engage a part of the jaw members.

5. A device of the class described comprising a pair of jaw members hingedly connected together, a wedge block located between the jaws and pivoted thereto, and reducer means adapted to be placed between the j aws and the rail and engaging the sides and top of the rail head for making the device fit a smaller sized rail.

6. A device of the class described comprising a pair of jaw members hingedly connected together, a wedge block located between the jaws and pivoted thereto, a shoe pivotally connected with one end of the block, an extension formed at the end of the block and acting as a handle, an extension formed at the other end of the block adjacent its lower edge and adapted to leave a. space between itself and the rail for receiving a bar and the shoe having grooves in its outer face for receiving a. bar for forcing the wheel away from the shoe. I

In testimony whereof I affiri my signature.
